Cisco Exam Questions

Which statement is true for this switch?

Refer to the exhibit. The show vtp status command is executed at a switch that is generating the
exhibited output. Which statement is true for this switch?

A.
The switch forwards its VLAN database to other switches in the ICND VTP domain.

B.
The configuration revision number increments each time the VLAN database is updated.

C.
The switch forwards VTP updates that are sent by other switches in the ICND domain,

D.
The VIAN database is updated when VTP information is received from other switches.

Explanation:
Switches in transparent mode don’t participate in the VTP domain or share its VLAN database, but
they’ll still forward VTP advertisements through any configured trunk links.
VTP is organized into management domains or areas with common VLAN requirements. A switch
can belong to only one VTP domain. Switches in different VTP domains do not share VTP
information. Switches in a VTP domain advertise several attributes to their domain neighbors.
Each advertisement contains information about the VTP management domain, VTP configuration
revision number, known VLANs, and specific VLAN parameters.
From the output of the command how vtp status provided in the exhibit, we know that the VTP
mode of the switch is the transparent mode.
Transparent mode does not allow the switch to participate in VTP negotiations. Thus, a switch
does not advertise its own VLAN configuration, and a switch does not synchronize its VLAN
database with received advertisements. VLANs can still be created, deleted, and renamed on the
transparent switch. However, they will not be advertised to other neighboring switches. VTP
advertisements received by a transparent switch will be forwarded on to other switches on trunk
links.
